Let's divide 121299 by 9
Our goal is to divide 121299 by 9.

Going ahead to step 1:
The number 9 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 9

Advancing to step 2:
The number 9 fits into 12 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 9 from 12, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 9

Going ahead to step 3:
31 divided by 9 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 27 from 31 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 9

On to step 4:
If we divide 42 by 9, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 134.0
Deduct 36 from 42 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 9

On to step 5:
69 divided by 9 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1347.0
The remainder is 6 after subtracting 63 from 69.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 9

Step 6:
The number 9 fits into 69 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 13477.0
If we take 63 away from 69, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
When dividing 60 by 9, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 13477.6
Subtract 54 from 60 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 9, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 13477.66
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 13477.66, and the remainder is 0.006.
